Appendix A. Daily Quality Assurance Checks

These checks must be performed by the first operator to use the room every day. It is the operators responsibility to ensure that if they are the first person to scan in a day, that they arrive in time to perform these checks before scanning.

A.1. Oxygen Level Checks

The Oxygen level of the scanner must be checked daily. The Oxygen monitor is in the MEG Backroom, see Figure 3.2. The value on the monitor should be recorded in the log book.

  1. A normal value for the O2 level is between 20% and 21%.
  2. If the level is below 20%, this needs to be reported.

    Contact reception, who will contact a member of staff. A staff member will then investigate the problem.

    [Warning]Warning
    If the O2 level falls below 19%, no-one should enter the MSR without being authorised to do so by a member of staff; as the O2 level unstable. There is a danger that the O2 may drop to below the 18% level, when the alarm sounds, and the MSR has to be evacuated.
